so i asked a few questions, and this is what he said....
Hello.
The usuall setup for this power is:
Gt28r,63mm exhaust,big intercooler,Bosch Green 360cc injectors and fuel pump upgrade.
With 1st stage cam (colombo or piper) we get that power with about 1.3bar steady boost.
With stock cam you may need about 1.55bar in order to get close to 240hp.
With wilder cam and 70mm downpipe we 've seen 255-260hp but the engine should be in perfect shape.
Let me know if you have more questions.
Thanks.
Stefanos
